GJ.6, yellow, rare example with almost dry impresion (without ink), completely blurred and illegible, franking a folded cover to Goya with pen cancel of Mercedes, fantastic!
GJ.14, notable brownish light lilac-rose color produced by effect of the dark gum on the original dark lilac-rose paper that can be observed in the central left border (which never had any gum), mint block of 4 with full original gum (+50%) with light hinge marks, very fresh, excellent quality, catalog value US$1,200 + 50% (original gum) = US$1,800. With Alberto Solari certificate
